48. two people push a box. one pushes with 35 n to the right, the other with 20 n to the left. what is the net force?
Answer
Explanation:
Step1: Define forces
Let the force to the right be positive, $F_1 = 35N$, and the force to the left be negative, $F_2=- 20N$.
Step2: Calculate net - force
The net force $F_{net}=F_1 + F_2$. Substitute the values: $F_{net}=35+( - 20)$. $F_{net}=35 - 20=15N$.
Answer:
$15N$
